Subject: [PATCH] Avoid implicit constant truncation
Date: Wed, 3 Mar 2010 11:01:07 +1100 [thread overview]
Message-ID: <1267574468-7609-1-git-send-email-imunsie@au.ibm.com> (raw)
From: Ian Munsie <imunsie@au.ibm.com>
When building on 64 bit platforms, the compiler throws the following
warning:
drivers/pci/probe.c:197: warning: large integer implicitly truncated to unsigned type
This patch adds an explicit truncation to silence the compiler warning.
